An analytical study is presented of the mean and turbulent characteristics of axial turbulent wakes behind a rotating fan. Simplified solutions are presented governing the mean radial and axial velocity profiles and their decay rate. An estimate is made of the relative order of magnitude of various turbulence quantities. The effect of rotation on the turbulence structure is described. Sufficient physical interpretations and explanations are presented for insight into and formulation of the problem.
